I like how the fan boys blame the customer. In the end after profound contemplation, I feel they're right we are to blame. In the future we should stop buying the products since we're to blame for buying them.
.....Well...yeah. Before I bought the game I checked to see if they made any mention of the features mentioned in that video...they didn't....and since they spent so much time going over what was available, I knew it'd been cut for whatever reason. Again...this is just like the person who got angry at DAO for not having Multilayer. If you aren't willing to do the research....or wait and make sure the very features you want are in the game then I don't see why I should be showing you any sympathy.
Something similar happened before ME 1...they showed that the games conversations would allow interrupts in the E3 2006 video....that didn't occur until ME 2 but I noted it's absence in the first game. It wasn't a deal breaker and it wasn't a reason to start complaining about false advertising.
